A falling ball viscometer determines fluid viscosity by measuring the time it takes for a precisely sized sphere to fall a set distance through the fluid. The sphere’s descent speed is influenced by the fluid’s resistance, allowing for viscosity calculation based on factors like sphere size, density, and fall time. Our viscometers with optical sensors operate by precisely timing the descent of a sphere through a fluid. Optical sensors, strategically positioned along the fluid column, detect the sphere’s passage as it blocks the light. By recording the time taken for the sphere to traverse specific distances, the instrument calculates the terminal velocity. This velocity, combined with the sphere’s properties and fluid density, allows for accurate viscosity determination.
